The terminology used in "Installation of LibreOffice 3.3 on Macintosh" is incorrect
http://www.libreoffice.org/get-help/installation/macintosh/
"Open the downloaded DMG file by double-clicking on it in the Downloads folder, or single
clicking on the Taskbar launcher drawer corresponding to Downloads (on a standard Macintosh
installation set-up, it is usually on the right-hand side of the task bar)."
There is no "Taskbar" on a Mac. The correct term is the "Dock".
There is no "launcher drawer". An icon for the Downloads folder is located in the Dock. (Folders in the Dock are referred to as “stacks.”)
Please use correct terminology for Macs. Incorrect terminology will cause confusion for inexperienced users, and make experienced users laugh at you and dismiss using your product.
